Oil Analysis | Applications | DDS Calorimeters

Oils are a non-volatile substance. In general they are not measured frequently because they are very consistent and uniform. Other oil properties are more important than the calorific value, such as taste or viscosity. If an oil is measured in an oxygen calorimeter, then the procedure would be the same as a solid substance. The weight of a crucible is zeroed and a small amount of approximately 0.5 gram of sample is put into the crucible, avoiding oil on the rim or outside crucible walls. Then the DDS cotton thread is attached to the firing wire (always use genuine CAL3K consumables), the crucible is put into the holder, and the oxygen vessel is closed, put into the CAL3K calorimeter and then automatically filled with oxygen. Five to 7 minutes later results are displayed on the LCD screen of the CAL3K.

Coal Analysis

The coal industry is the traditional application of calorimeters because coal has a variety of properties, apart from being black.

Explosives Analysis

Only explosives which can be ignited by heat from the calorimeter's firing circuit can be tested in the oxygen calorimeter.

Fuel Analysis

As a general rule, volatile fuels are measured very seldom because they are very consistent.

Cement Manufacturing

Isothermal calorimeters have been known to test the reaction of cement on hydration. Determining the heat of hydration of cement is important and traditionally, the heat of hydration has been determined by measuring the heat of solution.
